Up to twenty-five-year survival after aortic valve replacement with size 19 mm valves

Long-term survival was investigated in 202 patients who underwent isolated aortic valve replacement (AVR) with 19 mm valves. There were 171 women with a mean age of 69"9 years and 31 men with a mean age of 64"13 years. Patients had a mean body surface area of 1.61"0.13 m . Patient–prosthesis mismatch was moderate in 196 and severe in six patients. The mean follow-up for all patients was 2 78 months. There were 79 late deaths. The actuarial survival rates for all patients were 95"1% at 1 year, 75"2% at 5 years, 56"2% at 10 years, 41"2% at 15 years, 34"3% at 20 years and 34"2% at 25 years. Patients over 70 years old had a lower survival rate (Ps0.0001). There were significant differences between ejection fraction (EF) )55% and EF -55% (Ps0.0305). AVR with 19 mm valves appeared to provide satisfactory mid-term survival. Age and low EF were risk factors for shorter survival. 2010 Published by European Association for Cardio-Thoracic Surgery.
